Censorware and less/least restrictive means

Seven years ago, many advocates were arguing that Internet filters
were a "less restrictive alternative" to criminal laws banning
"indecent" speech on the Internet. But some prescient ones opined that
filters would actually be even worse. Despite the chilling tenor of
the Supreme Court argument in US v. ALA, one hopes that at least five
of the justices will come to the same conclusion.
